Physocarpus  plant named ‘Podaras 1’

ABSTRACT

A new and distinct cultivar of  Physocarpus  plant named ‘Podaras 1’, characterized by its compact and upright plant habit; freely branching habit; dense and bushy habit; dark brown-colored leaves; good garden performance; and tolerance to Mildew.

Botanical designation: Physocarpus opulifolius.

Cultivar denomination: ‘PODARAS 1’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Physocarpus plant, botanically known as Physocarpus opulifolius and hereinafter referred to by the name ‘Podaras 1’.

The new Physocarpus plant is a product of a controlled breeding program conducted by the Inventor in Ithaca, N.Y. The objective of the breeding program is to create new compact Physocarpus plants with unique foliage colors, types and textures.

The new Physocarpus plant originated from an open-pollination on May 10, 2006 of an unnamed seedling selection of Physocarpus opulifolius, not patented, as the female, or seed, parent with an unknown selection of Physocarpus opulifolius, as the male, or pollen, parent. The new Physocarpus plant was discovered and selected by the Inventor in August, 2008 as a single flowering plant within the progeny of the stated open-pollination in a controlled environment in Ithaca, N.Y.

Asexual reproduction of the new Physocarpus plant by cuttings in a controlled environment in West Chicago, Ill. since February, 2009 has shown that the unique features of this new Physocarpus plant are stable and reproduced true to type in successive generations of asexual reproduction.

SUMMARY OF THE INVENTION

Plants of the new Physocarpus have not been observed under all possible environmental conditions. The phenotype may vary somewhat with variations in environment and cultural practices such as temperature and light intensity without, however, any variance in genotype.

The following traits have been repeatedly observed and are determined to be the unique characteristics of ‘Podaras 1’. These characteristics in combination distinguish ‘Podaras 1’ as a new and distinct cultivar of Physocarpus:

-   -   1. Compact and upright plant habit.     -   2. Freely branching habit; dense and bushy habit.     -   3. Dark brown-colored leaves.     -   4. Good garden performance.     -   5. Tolerant to Mildew.

Plants of the new Physocarpus can be compared to plants of the female parent selection. Plants of the new Physocarpus differ from plants of the female parent selection in the following characteristics:

-   -   1. Plants of the new Physocarpus are more compact and denser         than plants of the female parent selection.     -   2. Plants of the new Physocarpus and the female parent selection         differ in leaf color as plants of the female parent selection         have dark burgundy-colored leaves.

Plants of the new Physocarpus can be compared to plants of the Physocarpus opulifolius ‘Diablo’, not patented. In side-by-side comparisons, plants of the new Physocarpus differed from plants of ‘Diablo’ in the following characteristics:

-   -   1. Plants of the new Physocarpus were shorter than and not as         open as plants of ‘Diablo’.     -   2. Plants of the new Physocarpus and ‘Diablo’ differed in leaf         color as plants of ‘Diablo’ had dark burgundy-colored leaves.

BRIEF DESCRIPTION OF THE PHOTOGRAPHS

The accompanying colored photographs illustrate the overall appearance of the new Physocarpus plant showing the colors as true as it is reasonably possible to obtain in colored reproductions of this type. Colors in the photographs may differ slightly from the color values cited in the detailed botanical description which accurately describe the colors of the new Physocarpus plant.

The photograph on the first sheet comprises a side perspective view of a typical plant of ‘Podaras 1’ grown in a container.

The photograph on the second sheet is a close-up view of a typical plant of ‘Podaras 1’.

DETAILED BOTANICAL DESCRIPTION

The aforementioned photographs and following observations, measurements and values describe plants grown during the spring and summer in one-gallon containers in an outdoor nursery in Abbotsford, British Columbia, Canada and under commercial practice. Plants were six months old when the photographs and description were taken. In the following description, color references are made to The Royal Horticultural Society Colour Chart, 2007 Edition, except where general terms of ordinary dictionary significance are used.
